GENE SILIENCING
Gene silencing is something that most people do not know about. It is part of molecular biology which is things to with the natural body and life but to a minute size. Gene silencing was developed and still developing by the RNAi team at CSIRO in Australia which was led by a British-Australian virologist and geneticist named Peter Waterhouse. This team of a few also had significant contributions from Ming-Bo Wang who helped Peter Waterhouse develop this technique. This technique is an innovation of Gene Shears and was discovered during the 1990s.
Gene Silencing is “the process of reducing or switching off the activity of a single gene”. A gene is like a coded instruction in your body which is passed down through families. These

What Gene Silencing does is it intercepts the mRNA on its journey towards the protein or translation. This effectively decreases that type of protein being developed. This is done by a specifically modified molecule which is programmed to go and “specifically identify and break down the mRNA carrying instructions.” An easier way to explain this is imagining the gene is a laser pointer, the molecule as a Lego brick and the mRNA as the laser. Usually the laser pointer would collect the electric power to fire the laser to its destination. If you put the Lego brick in front of the laser pointer somewhere, the laser will not reach its final destination. This is the same idea with the mRNA and the …show more content…
Both his parents were primary school teachers, until when his older sister was born where his mum stopped working. He has 4 other siblings including a younger brother and 3 younger sisters. Ming-Bo went to primary and middle school during the last few years of ‘China’s cultural revolution’ and so luckily his senior years (1977-1980), china resumed their normal education and was able to receive the best education in the country including other 200,000 people. He was able to enter the ‘prestigious’ Beijing Peking University. He studied chemistry for 4 years and became a master in it. He is life experiences

    And consequently, to understand gene expression is to understand why these mutations can have such grave effects on an individual. For DNA to direct cellular processes, it must be transcribed and translated, The AP Biology Curriculum Framework explains. It goes on to say that “the products of transcription and translation play an important role in determining metabolism, i.e. cellular activities and phenotypes.” So if “changes in a nucleotide sequence, if present in a protein-coding region, can change the amino acid sequence of the polypeptide” (AP Biology Curriculum Framework, p. 37), changes to these essential proteins prevents cellular activities from being performed. The field of gene therapy began due to knowing about mutations and their effects on gene expression.…

    The Basics of Gene Expression and Control Genetics is a very diverse field of science, because it encompasses so many aspects of not only what happens inside organisms, but also how offspring relate to parents and ancestors and many other processes. Although every bit of genetics is important, many things in an organism would not be possible without the expression of genes. Through expressions of genes, organisms provide for themselves and "fulfill" what is the basis of their genetic possibility. These processes of transcriptional gene control, translational gene control, and post-translational gene control helps make key components that help an organism function in many ways.…

    Contrary to what one would expect based on the title of her book, The Forever Fix: Gene Therapy and the Boy Who Saved It, Ricki Lewis pens a narrative science focused on the milestones in the history of gene therapy, not just one success story (Lewis, 2012). Corey Haas, the boy who regained his vision after being sentenced to a life of blindness, is only one of the medical miracles mentioned; the book also devotes itself to presenting the theory and procedures behind gene therapy. As a supplement to the curriculum of the AP Biology course, the major biological concept of gene therapy in The Forever Fix: Gene Therapy and the Boy Who Saved It relates specifically to the third big idea in the AP Biology curriculum framework’s four major points.…

    Summary: ״The CRISPR Conundrum״ “The CRISPR Conundrum” (2016) by Mary Bates, describes “CRISPR”- clustered regularly interspaced short palindromic repeats, which is a new revolutionary technology in genetic engineering. It is a kind of molecular scissors that can be programmed to snip specific bits of DNA. The article talks about the advantages of CRISPR, yet it describes CRISPR’s disadvantages as well. On the one hand, CRISPR is a cheap and precise technique to edit the DNA of animals, plants and even humans.…

    What if you had the choice to save an embryo would you do it if that meant you could have more than one child? Imagine you have a genetic disease and the only option to have children is using the in-vitro fertilization method. This means taking your viable embryos testing and choosing the one that is "healthy" without the disease to have a child while the others get disposed. But, what if you could save them by genetically modifying the DNA sequences using gene technology within the embryos to make it so that they no longer had the disease? Ronald M. Green the author of "Building Baby from the Genes Up” uses his experiences in biomedical ethics to tell his readers that the main reason as to why people are against genetic modifications is because…

    It is beyond a doubt that the founding fathers could ever conceive an American society like the one we are living in today. The discovery of the structure of DNA marks a significant landmark in medical history. This has open the doors to a new realm that deepen our understanding of biological systems and promises a future that once was an abstract idea in science fiction novels. A challenge that my generation is facing is answering whether genetic modifications are ethical. Despite the ongoing debates, it is remarkable that this type of science is even possible, partially because of the universality of DNA.…

    The Ethics of Prenatal Genetic Modification Genetic engineering is a method of altering the genetic makeup of an organism with the intention of improving the organism. The technology that is used for this modification is still in its early stages, but was intended to be used in the manufacturing of insulin, various hormones, and antibodies, as well as disease research and gene therapy. This technology is beginning to encroach into reproduction, where it has the potential to be used to prevent certain sex-linked diseases and screen for embryos that are predisposed to certain genetic conditions. Once this technology is integrated into reproductive processes, a door will be opened for parents to have “designer babies,” which is a term that describes…

    The “Bubble Boy” gene therapy experiment is one of the experiments on gene therapy. Gene therapy is still a moral debate to this day, some people beg the question if it’s okay to use gene therapy or what would it do to the human body which are all great questions. The discussion will be on whether the “Bubble Boy” gene therapy experiment was ethical or not and if the treatment was worth the risk. Basically the “Bubble Boy” experiment was on children suffering from the bubble boy disease which is a severe combined immunodeficiency that can possibly lead to death (Vaughn, 260). Sixteen children suffered from this disease so the researchers decided to try out the new treatment on them, they received gene therapy for nine years (Vaughn,260).…

    Gene editing is the alteration of genes in germ cells which become either sperm or eggs and are inheritable to future generations. Genetic editing has been used in agriculture to enhance crops, it is now being explored in humans too. This technology could potentially eradicate genetic diseases and prevent future generations from passing it on. Gene editing is done through the CRISPR-Cas9 system, where the embryo is edited to the desired outcome. It identifies and attacks the viral DNA and then it changes the targeted DNA strand that can be replaced or turned off.…
